Our Smooth Leash Hack Wallet Chain is a solid, weighty chain that we've "hacked up" with our Knight Hack Plating, which is a dark, rough, distressed antique finish. Similar to a leash chain, but these links are smooth instead of filed. This is a heavy chain, with superior quality and styling. Our hardware (sturdy snap hook and dual wallet hook end-pieces) adds approximately 3" to the listed length of the Wallet Chain.Chain links measure 3/4" X 1/2", with the wire thickness approx. 4mm. 100% Made in the USA.
